摘要： A motor vehicle powertrain includes a multiple speed transmission including a first lube circuit that supplies hydraulic lubricant to components of the transmission, a first oil sump, and a first pump driveably connected to an engine for supplying oil at a first pressure to the lube circuit, a transfer case including a first output, a second oil sump located in the transfer case, a second pump located in the transfer case and driveably connected to the first output, and a check valve for alternately opening and closing a connection between the first pump and the lube circuit and for opening and closing a connection between the second pump and the lube circuit in response to differential pressure between an outlet of the first pump and an outlet of the second pump.
